Description

Известные устройства дл  поверки тензометров имеют недостаточно высокую точность измерений, что при современных требовани х испытательной техники часто  вл етс  крупным недостатком.The known devices for the calibration of strain gauges have an insufficiently high accuracy of measurements, which with modern requirements of test equipment is often a major drawback.

В предлагаемом устройстве перемещение подвижной опоры производитс  с помощью клина с микровинтом, что значительно повышает точность измерени .In the proposed device, the movable support is moved by means of a wedge with a microscrew, which greatly improves the measurement accuracy.

На чертеже изображена принципиальна  схема устройства.The drawing shows a schematic diagram of the device.

Продольна  каретка } с миллиметровой шкалой плавно перемещаетс  при помощи микровинта по направл ющим станины 2. Величина перемещени  каретки измер етс  с помощью спирального .микроскопа 3, установленного над щкалой.A longitudinal carriage} with a millimeter scale is smoothly moved with the aid of a microscrew along the guides of the bed 2. The magnitude of the movement of the carriage is measured with the help of a spiral microscope 3 mounted above the scale.

К продольной каретке прикреплен клин 4, к которому прижимаетс  выступ поперечной каретки 5, котора  перемещаетс  в поперечных направл ющих станины. Клин рассчитан таким образом, чтобы при перемещении продольной каретки на 1 мк, поперечна  каретка переместилась на 0,1 мк.A wedge 4 is attached to the longitudinal carriage, against which the protrusion of the transverse carriage 5 is pressed, which moves in transverse guide beds. The wedge is designed so that when moving the longitudinal carriage by 1 micron, the transverse carriage moves by 0.1 micron.

Поперечна  каретка соединена с подвижной опорой 6, наход щейс  в одной плоскости с неподвилшой опорой 7.The transverse carriage is connected to the movable support 6, which is in the same plane as the non-supporting support 7.

На этих опорах при помощи специальных пружин могут быть укреплены в горизонтальных или вертикальных положени х повер емые тензометры .On these supports, with the aid of special springs, adjustable strain gauges can be fixed in horizontal or vertical positions.

Предмет изобретени Subject invention

Клиновое устройство дл  поверки тензометров (клиновой тензокалибратор ), имеющий подвижную и неподвижную опоры, отличающеес  тем, что, с целью повышени  точности измерений, перемещение его подвижной опоры производитс  при помощи клина с микровинтом, что позвол ет производить отсчет с точностью до 0,1 мк.A wedge device for calibration of strain gauges (wedge strain gauge), having a movable and fixed support, characterized in that, in order to improve the measurement accuracy, moving its movable support is performed using a wedge with a micro screw, which makes it possible to read out with an accuracy of 0.1 micron .
